Thick Foam on Top of Springs
This mattress combines a spring support core with a thick high density foam layer. The foam is compressed to a very dense state for extra durability. You get a product that does not develop body impressions over time. The high density foam provides a firm but comfortable sleeping surface. The springs underneath give the mattress extra support and bounce. This combination works well for people who like a firm feel. The foam also adds insulation and reduces spring feel through the top. Many plus sized sleepers prefer this mattress for its strong support.
Dense Foam for Firm Support
The foam layer in this mattress is made from high quality polyurethane material. You get a product that weighs more than a standard foam mattress. The high density means the foam has more material per cubic foot. This gives it a longer lifespan and better shape retention. The foam does not soften or break down as quickly as lower density types. The springs are made from tempered steel for consistent support. You will find this mattress handles heavy weight without bottoming out. The product is often recommended for people over 100 kilograms. Many mattress dealers stock this type for plus size customers.
